Safety Precautions & Declared Material
General Equipment Precautions
Caution
To avoid malfunctioning or personnel injuries, equipment or accessories/kits/plug-in unit
installation, requires qualified and trained personnel. Changes or modifications not expressly
approved by Cambium Networks could void the user's authority to operate the equipment.
Caution
Where special cables, shields, adapters and grounding kits are supplied or described in this manual,
these items must be used, to comply with the FCC regulations.
Caution
Use of controls, adjustments, or performing procedures other than those specified herein, may
result in hazardous radiation exposure.
Caution
When working with a RFU-C, note the following risk of electric shock and energy hazard:
Disconnecting one power supply disconnects only one power supply module. To isolate the unit
completely, disconnect all power supplies.
Caution
Machine noise information order - 3. GPSGV, the highest sound pressure level amounts to 70 dB (A)
or less, in accordance with ISO EN 7779.
Anti Static
Static electricity may cause body harm, as well as harm to electronic components inside the device.
Anyone responsible for the installation or maintenance of the RFU-C RFU must use an ESD Wrist
Strap. ESD protection measures must be observed when touching the unit. To prevent damage,
before touching components inside the device, all electrostatic must be discharged from both
personnel and tools.
Caution
In Norway and Sweden:
Equipment connected to the protective earthing of the building installation through the mains
connection or through other equipment with a connection to protective earthing – and to a cable
distribution system using coaxial cable, may in some circumstances create a fire hazard. Connection
to a cable distribution system has therefore to be provided through a device providing electrical
isolation below a certain frequency range (galvanic isolator, see EN 60728-11).
Utstyr som er koplet til beskyttelsesjord via nettplugg og/eller via annet jordtilkoplet utstyr – og er
tilkoplet et kabel-TV nett, kan forårsake brannfare. For å unngå dette skal det ved tilkopling av
utstyret til kabel-TV nettet installeres en galvanisk isolator mellom utstyret og kabel- TV nettet.
